Hi Guys, I installed what griffin calls a direct fit aluminum radiator with the custom built aluminum shroud and 2 spal 10" fans. Came with 2 relays. So, I wired the two fans placing the ground wires for each fan in a different location. I then wired the fan supply to the red feeds from each...

Question is if I install a shroud on my US Radiator and put a 16" spal fan, does the fan have to be offset, of can I just put it in the center of the aluminum shroud, which would be offset from the engine by about 2"? Would I be better off with the one 16" fan or I understand I can fit 2 10"...

Just getting ready to fill the aluminum radiator with the evans coolant. The thought occurred to me that because this block and aluminum heads are empty of coolant, should I remove the new thermostat I installed during assembly. My concern is a lack of coolant flow and possible damage to the...

just bought a set from Detroit muscle. There are two rubber bushings also enclosed. These bushings look as though they will not fit in the hose? Is there a trick to this?? Where do these bushings actually go to? They appear to be very very tight???

My 72 Demon 340 has only 2 1/2" of space from the front of the pulley to the face of the radiator core. I have a U S Radiator direct fit aluminum. I read some folks have 5" of space here? Where the hell am I losing 3" at. This is friggin crazy. Do I have a different year water pump when I...

Does anybody have an extra J bolt to hold the corner of my heater box for my 72 Demon. I seem to be missing mine? I look inside the door and there is a metal L bracket.

I am ugrading my Demon stroker motor with new a/c goodies. I seem to be a little tight on the fuel log routing. The alternator still needs to get installed. I was thinking of routing the fuel filter out the rear of the log and then use a 180 degree Russell fitting to run back along the valve...
